iSpring AAS2 Reverse Osmosis Water Filter Automatic Shut Off Valve Quick Connect, Whilte

This stopped my never-ending drain issue with my iSpring RO System I got back in 2013. When you refill your tank with pressure, this can make the drain problem show up a little easier.You can check if it's the ASO valve vs the check valve by turning off the tank valve, but leave the inlet valve open (that comes from your house water supply). If it continues to drain then the ASO valve could be bad.. If you do the opposite (turn on tank valve, off inlet water supply) and it stops draining then it's most likely the ASO valve.Some tips for installation:Make sure you buy extra RO tubing with this so you can put new tubing on at the same time, especially if your old ASO valve has screw on fittings like mine did.Push the tubes in pretty forcefully into the quick connect fittings, if you don't push past the rubber ring inside, it will leak at that fitting. You can take the little plastic lip piece out to see where the rubber ring is to get an idea of what you will need to push past. There are some good youtube videos on how to install these correctly if you are still stuck.Before you put the RO system back, leave it out for 10-15 minutes with everything turned on to make sure nothing leaks. If any of the quick connects are leaking, see the note above about pushing it past the rubber ring. You can use petroleum jelly if it's being really stubborn.

We all expect products we invest in to do the job, and iSpring RO systems will not disappoint - but what sets this company apart is the terrific technical support.Today, Nick simply and easily helped me troubleshoot and remedy a problem - honestly, so nice to know a company has talent like that and the desire to provide such great service.

Here you go, lessons I learned the hard way (my ASO valve would not operate correctly):1) Make SURE you understand the IN & OUT ports and hook up the lines correctly to ASO valve.2) Use ONLY hard lines to interconnect (dont use clear lines from home depot, they are too soft and valve wont shutoff correctly).3) Keep all hard tube lengths to ASO valve as short as possible.4) On all connections make sure the tubes push all the way down5) On all post carbon filters, post filters, etc...dont plug tubing directly into these filters, always use a push in connector first then push your tube into those connectors.I did all above and fixed my ASO valve RO system operation.

The one that came with the water filter system broke only after 5 months. I got a replacement and that one lasted longer, for a year and 8 months. We'll see how long the new one will last. As for how the device functions and the installation with the quick connect, it is great. Durability not as good.

My RO system was not turning off and I could hear the water trickling all day long. After some research I ordered this part. Before replacing, turn the valve off on the water supply and the RO tank. It took about 2 minutes to replace and now my RO systems shuts off when the tank is full.

It is one of the most important parts in the reverse osmosis system. The company's customer support is crucial. Thank you Nick, Sean and Michelle.

I had an issue with RO constantly draining. After doing some research, I read that the ASO might need replacing. Having only used iSpring replacement filters and parts the past few years, I decided to purchase the ASO from iSpring as well. As expected, I am very happy with the results. My RO system is fixed and iSpring provides excellent customer service. Highly recommend.

None of the ASOs on Amazon have any information about the dimensions between the ports on these ASOs. I have a Pentair, Freshpoint under sink RO system. The valve is fitted directly onto the posts in the manifold inside the unit. The post spacings are about 15/16” but this ASO is roughly 7/8”. So the only solution to make this one work is to put tubing between the manifold and the ASO which means it doesnt nest inside the housing any longer.Product dimensions and schematics are a basic requirement of any listing of mechanical devices yet no one seems to provide this any longer. The focus seems to be on making it easy to purchase and return without being easy to understand whether the product is actually a solution to the buyers’ problem. Web shopping has taken so many storefronts out of business, how does one find help with anything now?
